Abstract (en)

[origin: US2013305785A1] A method for making a vacuum insulated glass window assembly is provided in which an exposed end of a pump-out tube of a vacuum insulated glass window assembly is sealed using a laser that is applied to the end of the pump out tube in controlled sequential manner as opposed to a short duration, high-powered application of a laser. In particular, a method is disclosed in which a multiphase sequential variable power application of laser energy to an exposed end of a pump-out tube for controlled exposure times and decreasing laser trace diameters produces a more controlled melting of the tube glass to reduce or eliminate undesirable outgassing that may occur during a high-power short duration exposure of laser energy to the end of the pump-out tube to seal the tube.
